Abstract : A study was made of published radio data on 57 pulsars to determine specifications for an antenna and receiver system for the precise timing of pulsar pulses. The study attempted to optimize the frequency choice, the receiver system, and array size for a given choice of pulsars and timing error. An approximate theory was developed to relate antenna area and pulsar parameters to the timing error. The theory was tested against the pulsar data. Then an array was specified which would give a timing error of less than 100 microsec on 15 pulsars. These results could be used in a feasibility study of a portable navigation system dependent only upon natural extraterrestrial radio signals. (Author)
